The New Hotness

  • Raspberry Pi vs. MicroSD: Another One Bites the Dust

    The Raspberry Pi running the MPCNC recently seized up with baffling symptoms, which generally indicates the poor little MicroSD card serving as a “hard disk” has failed:

    Defunct Sandisk Ultra 32 GB MicroSD
    Defunct Sandisk Ultra 32 GB MicroSD

    I managed to open a terminal emulator, whereupon all of the non-built-in shell commands couldn’t be found.

    Proceed as before: binary-copy the entire MicroSD card to another one, pop it in the RPi, and it’s all good again.

    For the record, the new card is an unused Samsung Evo Plus. I do not understand the difference between the “Evo Plus” and “Evo+” branding, other than to suspect one of being a very good fake.

    In round numbers, MicroSD cards seem to last a year under what seems like not-too-demanding service; I’m not running the MPCNC all day, every day.
